Java输出杨辉三角10行

下面是输出10行杨辉三角的Java代码：

public class YangHuiTriangle {
    public static void main(String[] args) {
        int n = 10;
        int[][] triangle = new int[n][];
        triangle[0] = new int[]{1};
        for (int i = 1; i < n; i++) {
            triangle[i] = new int[i + 1];
            triangle[i][0] = 1;
            for (int j = 1; j < i; j++) {
                triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j];
            }
            triangle[i][i] = 1;
        }
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < triangle[i].length; j++) {
                System.out.print(triangle[i][j] + " ");
            }
            System.out.println();
        }
    }
}

输出结果如下：

1 
1 1 
1 2 1 
1 3 3 1 
1 4 6 4 1 
1 5 10 10 5 1 
1 6 15 20 15 6 1 
1 7 21 35 35 21 7 1 
1 8 28 56 70 56 28 8 1 
1 9 36 84 126 126 84 36 9 1
